Laymans take (as a retired LL)
I presume your lease addresses that unit has AC?
If AC now works it not an issue!
You need to look up and follow with some aggression and assertiveness the GA landlord tenant laws as to "repair and deduct"--prior written notice to LL is critical
Usually a running toilet is due to a 50 cent washer or a $1.00 flapper that takes about 12 minutes for a person with a 6th grade education to replace ---but you get billed say $125 to have a licensed pro come do it.
I doubt compensation for inconvenience is recoverable.
But if toilet won't work properly and you notice LL in writing as per law and he is way too slow and you repair and deduct you are on safe side of the law! And he eats a $125 bill for an otherwise minor item
